Lifesaver' Bottle Purifies Water in
Seconds By Allison Barrie
There's
a reason they call it the "Lifesaver."
On the outside, it looks like an ordinary sports bottle.
On the inside, there's a miracle: an extremely advanced
filtration system that makes murky water filled with
deadly viruses and bacteria completely clean in just
seconds.
The Lifesaver removes 99.999 percent of water-borne
pathogens and reduces heavy metals like lead, meaning
even the filthiest water can be cleaned — immediately.
It will be a boon to soldiers in the field, so it's
winning accolades from the military.
It also stands to revolutionize humanitarian aid. It
could be the first weapon in the fight against disease
after a natural disaster, like the one in Myanmar this
week.
I attended the Lifesaver’s launch at DSEi London, the
world’s largest arms fair. Its inventor provided a pool
of dirty pond water as a test subject, and I drank some
after it was filtered. Not only did it look pure once it
passed through the Lifesaver, it tasted pure, too.
The process takes only 20 seconds and is simple enough:
scoop some water, pump it through the filter and you’re
ready to go. The instructions are displayed in pictures
on the side of the bottle, so it can be used by anyone,
removing the language barrier.
Outdoor enthusiasts may find it useful, but the Lifesaver
is perfect for the military. The bottle is designed to
“scoop and go,” so soldiers won’t have to carry the added
weight of clean bottled water. They can pick some up out
of any source and keep moving.
As an added bonus, the bottle can shoot a pressurized jet
of water from any angle, which will be useful for washing
wounds free of contaminants and debris.
Other filters use ceramic pores and can’t catch most
bacteria and viruses, but the Lifesaver uses microscopic
pores a mere 15 nanometers across — about one-hundredth
the width of a spider’s silk — narrow enough to stop the
tiniest threats. That means virtually nothing — not even
bacteria and viruses — can get through.
And since the bottle uses a carbon filter, it makes water
safe and sterile without any chemicals, removing that
iodine or chlorine taste.
The bottle weighs about 1.5 pounds and can filter one and
a half pints of clean drinking water each go. Its
replaceable filter can handle more than 1,500 gallons of
dirty water before it has to be replaced. And since it
won’t process any water once the filter has expired, it
will be impossible to drink contaminated water by
mistake.
Michael Pritchard, a British entrepreneur, designed the
Lifesaver in the wake of freshwater shortages that
followed the 2004 tsunami and Hurricane Katrina.
Delivering bottled water to disaster areas is difficult,
especially in places like Myanmar, where the government
is currently interfering with efforts to distribute
supplies and aid. If disaster victims had access to the
Lifesaver, they could have ongoing access to clean water
without the need for airlifts.
Delivering those planeloads of water is expensive, too. A
U.S. Army study revealed that the cost of delivering
bottled water to Afghanistan was $4.69 per gallon.
Pentagon figures on Hurricane Mitch showed the cost of
air freight was even higher: $7.60 per gallon.
Just one Boeing C-17 transport plane full of Lifesaver
bottles would provide 500,000 people with access to safe
drinking water for up to 16 months — saving millions and
saving lives. Original article on:
